From my earlier testing, it's a bit too conservative, and if you make it even more conservative, it may end up reducing the effectiveness of I/S. But even if not used for avoding I/S, it can be used to pick whether to invert the phases, where it was clearly more stable. > This method is naive but it handles spikes better since a single spike in > one channel will only cause a single phase to switch among a reasonably > sized number of coefficients summed over. The spike will be very audible though, and it should be ok if it dominates. I don't remember any case where it was mistaken when I was testing. Do you have a sample that exhibits this? _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
